Last Thursday, walking north along the Newmarket/Barrie GO tracks, north of Dupont St.
There's only a single active railway track here, but it's interesting to look at all the other bits of abandoned tracks along here. It's a narrow railway corridor (much smaller than the Georgetown corridor to the West of here), but it still used to have multiple tracks and spurs to service the industry along its path. Many of these old tracks and spurs just appear and disappear quickly into old factory buildings, piles of rubbish, or overgrown bushes.
